Studies on Molecule-Exchanging Energy on Surface of Binary Surfactant Aqueous Solutions with Dimensional Crystal Model

Abstract

Abstract: The relationship between activity coefficient and molecule-exchanging energy of surfactants in the surface monolayer of binary surfactant aqueous solutions has been deduced with the help of two-dimensional crystal model. The results show the relationship between the synergism of surfactants and the molecule-exchanging energy. Through the parameter of molecule interaction( β_s), the value of the molecule-exchanging energy can be obtained by equation ε =2.3×10^-24 β_s T that has been examined with six typical surfactant systems.

Key words: Surfactant, Molecule exchanging energy, Parameter of molecule interaction( β_s)
